Meth Acrylic Pressure-sensitive Adhesive Foam and Method for Producing the Same
Patent - A meth acrylic pressure-sensitive adhesive foam reduced in the amount of a foaming adjuvant compared with the conventional foam and having a high air bubble content, and a method for producing the same are provided. The foam includes a partial polymer having a one or more alkyl meth acrylate monomers having one reactive unsaturated group, the alkyl group having 12 or less carbon atoms, b a monomer for crosslinking, which is copolymerizable with the component a, and c a copolymer of the component a and the component b; a thermally conductive filler; and a foaming adjuvant containing surface modified nanoparticles having a particle diameter of 20 nm or less, wherein a crosslinked structure containing the component c is formed in the curable composition. More particularly, the present disclosure relates to a thermally conductive (meth)acrylic pressure-sensitive adhesive foam and a method for producing the same.
